Research On H6 Topology Inverter Based On Daul Boost

With the rapid development of the mobile Internet, the traditional industry has been penetrated, which has caused the revolutionary changes of the industry, and the traditional industry to the consumer industry as the core, improve the life experience of people.Aiming at the high speed development of distributed photovoltaic power generation and mobile Internet, a kind of photovoltaic grid connected inverter which is suitable for large-scale promotion, high efficiency and data transfer function is needed. The difference between family and plant type of photovoltaic grid connected power system is characterized in that the power level is not the same, but family distributed generation system can overcome the disadvantages of dispersed sunshine, so in flexibility and economy are than the PV power plant has more advantages, while family of grid connected inverter, using top grade, two-way, improve the input power at the same time, the inverter has small volume, light weight, high efficiency and low cost, has great potential of development.First of all, the use of new energy to promote social and economic development of a revolutionary significance, photovoltaic power generation is the world is now vigorously develop new energy, to master the technology to promote economic reform and development. Through introducing the status of domestic and international PV grid connected inverter, the bottleneck problem of domestic photovoltaic inverter technology, and the analysis of domestic and foreign to the distributed PV grid connected power generation strategy is different, a low cost, stable and reliable DSP based on dual core Boost front stage dual path of non isolated photovoltaic grid connected inverter.In this paper, a new type of single phase H6 bridge photovoltaic grid connected inverter with non isolated H6 topology is adopted to reduce the common mode current. The main control board uses two TMS320F28035 as the control core, the Boost as the first level H6 full bridge inverter control and the grid connected current inverter control, and the other is H6 as the communication module.In this paper, we build a grid connected test platform, for the maximum power tracking control, the back level inverter, intelligent control algorithm, and applied to photovoltaic grid connected inverter, improve the data communication ability, so that the inverter can become a family of intelligent hardware, users can query real-time information.
